Level 50
Grenades • Refill IVF
PLAYSTYLE
Jack’s affinity with weapons makes him a viable choice for anyone who likes to deal damage with their guns and wants to live the assault fantasy.
This build is pretty straightforward as well. You want to throw grenades that are massively boosted by Just Compensation, and you can pretty much one-shot a lot of level 50 bosses. Apart from that, weapon-swapping guns will give you the bonuses of previous weapon manufacturers, making it very useful to constantly switch back and forth between your weapons. This is why we have two Refill IVFs as well, so you can get that insane fire rate. So, pretty simple, just lob grenades, shoot enemies, and call in digi-clones when you can.
SOLO
This is a strong build at level 50, and has the potential to one-shot a lot of bosses around this level. There really isn’t much to explain here outside the usual game plan, but you are basically a walking tank.
COOP
Similarly, this is a great build to support a team and if you bring in Athena and Nisha along you might as well play the game blindfolded to experience even a shred of challenge. There’s not much to say here, but Jack’s digi-clones can be pretty handy as distractions, but you’ll barely think about them.
